The documentation for Context states that this is just as good:
// If Done is not yet closed, Err returns nil.
// If Done is closed, Err returns a non-nil error

Now that we're not losing the scrape cache across failed
scrape, a scrape that continually failed but had varying
series or metadata (e.g. timestamps in metric names,
plus hitting smaple_limit) would grow the cache indefinitely.
Add some code to catch that, and flush the cache anyway.

The goal is to remove almost all references to the
golang.org/x/net/context package.
github.com/gogo/protobuf => v1.2.1
google.golang.org/grpc => v1.19.1
github.com/grpc-ecosystem/grpc-gateway => v1.18.5
It also replaces github.com/cockroachdb/cmux by github.com/soheilhy/cmux
because of [1] which fixes#3909 incidentally.

Like `promtool check config <path/to/foo.yaml>`, which resolves relative
paths inside foo.yaml to be relative to `path/to`, this now makes
`promtool test rules <path/to/test.yaml>` do the same thing.

i) Uses the more idiomatic Wrap and Wrapf methods for creating nested errors.
ii) Fixes some incorrect usages of fmt.Errorf where the error messages don't have any formatting directives.
iii) Does away with the use of fmt package for errors in favour of pkg/errors

hashicorp/serf is only required as a dependency of hashicorp/consul so
bumping the version has no direct consequence for Prometheus itself. The
net gain is that we don't depend anymore on launchpad.net/gocheck which
required the bzr binary to be installed.

* promparse: sort all labels when parsing
Some label names might start with an uppercase letter in which case it
needs to come before __name__. Without this it means that we are not
maintaining the same invariant that all label names should be sorted in
such cases.
Amend the tests to check this problem automatically. Without the change
the tests do not pass.

* reload: copy state on both name and labels
Fix https://github.com/prometheus/prometheus/issues/5193
Using just name causes the linked issue - if new rules are inserted with
the same name (but different labels), the reordering will cause stale
markers to be inserted in the next eval for all shifted rules, despite
them not being stale.
Ideally we want to avoid stale markers for time series that still exist
in the new rules, with name and labels being the unique identifer.
This change adds labels to the internal map when copying the old rule
data to the new rule data. This prevents the problem of staling rules
that simply shifted order.
If labels change, it is a new time series and the old series will stale
regardless. So it should be safe to always match on name and labels when
copying state.
